Resolution: Select recording resolution.

NTSC: 704x480 / 704x240 / 352x240

PAL: 704x576 / 704x288 / 352x288

Normal: Frame rate in images per second for continuous recording. It is important to keep track of the normal recording resources being allocated at each hours of the day. Increasing the Normal recording resolution and/or rate can inadvertently request more recording resources than the DVR is capable of delivering, or allocate so much of the DVRs resources that there is no excess available for increased FPS rate and/or resolution in response to an Event.

The speed is limited by the maximum total recording capacity of the DVR as allocated across all the installed cameras, with an upper limit of 30 FPS (NTSC – 25 PAL) per individual camera (real time recording). The DVR is capable of recording 480 CIF (352x240) sized frames per second (NTSC; 400 PAL); each 704x240 image (2 CIF) per second requires allocation of two of those CIF frames from the overall capacity of 480 CIF frames, and each 704x480 image (D1 or 4 CIF) per second requires allocation of four of the CIF frames from the overall capacity. Thus the DVR can record a combination of CIF, 2 CIF and 4 CIF images, with different combinations of image size/resolution and different FPS rates on different cameras, so long as the total CIF equivalents allocated is not greater than 480 CIF per second. Choices for possible record speeds are 30, 15, 10, 7.5, 5, 3, 2 and 1 FPS.

Examples:

16 cameras at CIF resolution at 30 FPS: 16x30=480 FPS

2 cameras/4CIF/30FPS plus 5 cameras/2CIF/15FPS plus 9 cameras/CIF/10FPS:

2x4x30+5x2x15+9x1x10= 240+150+90 = 480

2 cameras/4CIF/30FPS plus 2 cameras/2CIF/30FPS plus 12 cameras/CIF/10FPS:

2x4x30+2x2x30+12x1x10= 240+120+120 = 480

In these examples, the recording capacity of the DVR is fully allocated to normal recording, with no reserve capacity for increasing image size and/or FPS rate in response to a motion or alarm event (see next item). Since EverFocus DVRs have the capability to change recorded image size and FPS rate in response to events, it may be advisable to reserve some recording capacity for event response. For example:

2 cameras/4CIF/10FPS plus 5 cameras/2CIF/10FPS plus 9 cameras/CIF/5FPS:

2x4x10+5x2x10+9x1x5= 80+100+45 = 225 allocated with 255 in reserve.

Event: Maximum desired frame rate in frames per second (FPS) for event recording; if more than one camera requires simultaneous event recording, the total for all cameras cannot exceed the maximum available FPS for the DVR at the corresponding resolution setting, and the available FPS may be divided across the cameras responding to an event. In the example above, with 225 CIF FPS allocated and 255 CIF FPS remaining, it would be possible to increase the FPS rate on the two 4 CIF cameras from 10 FPS to 15 FPS and also increase the resolution and rate of the five 2 CIF cameras to 4 CIF and 15 FPS, with 15
